4.2 Connector check
1. Visual inspection of the connection:
– Check that the connector is connected correctly and that the male and female parts of the connection are correctly
coupled.
2. Visual inspection of the area around the connection:
– Check the condition of the mounting (pin, strap, adhesive tape, etc.) if the connectors are attached to the vehicle.
– Check that there is no damage to the wiring trim (sheath, foam, adhesive tape, etc.) near the wiring.
– Check that there is no damage to the electrical wires at the connector outputs, in particular on the insulating material
(wear, cuts, burns, etc.).
Disconnect the connector to continue the checks.
3. Visual inspection of the plastic casing:
– Check that there is no mechanical damage (casing crushed, cracked, broken, etc.), in particular to the fragile
components (lever, lock, terminal locations, etc.).
– Check that there is no heat damage (casing melted, blackened, deformed, etc.).
– Check that there are is no dirt (grease, mud, liquid, etc.).
4. visual inspection of the metal contacts:
(The female contact is called CLIP. The male contact is called TAB).
– Check that there are no bent contacts (the contact is not inserted correctly and can come out of the back of the
connector). The spring contact of the connector when the wire is pulled slightly.
– Check that there is no damage (tabs bent, clips open too wide, blackened or melted, etc.).
– Check that there is no oxidation on the metal contacts.
Visual inspection of the sealing:
(Only for watertight connectors)
– Check for the seal on the connection (between the 2 parts of the connection).
– Check the seal at the back of the connectors:
– For unit joints (1 for each wire), check that the unit joints are present on each electrical wire and that they are
correctly positioned in the opening (level with the housing). Check that plugs are present on openings which are
not used.
– For a grommet seal (one seal which covers the entire internal surface of the connector), check that the seal is
present.
– For gel seals, check for gel in all of the openings without removing the excess or any protruding sections
(it does not matter if there is gel on the contacts).
– For hotmelt sealing (heat-shrink sleeve with adhesive), check that the sleeve has shrunk correctly on the back
of the connectors and electrical wires, and that the hardened adhesive is evident from the wire ends.
– Check that there is no damage to any of the seals (cuts, burns, significant deformation, etc.).
If a fault is detected, consult Technical Note 6015A, Repairing electrical wiring. Note:
Carry out each requested check visually. Do not remove a connector if it is not required.
Note:
The check is carried out on the 2 parts of the connection. There may be 2 types of connections:
– Connector/Connector.
– Connector/Device.
